Abstract: A device includes an elongated hollow member having an open distal end for receiving tissue therein and at least one exterior groove for loading at least one ligation band thereon. The device also includes a band deployment sleeve slidable over the exterior of the hollow member and configured to move from a radially expanded position to a radially contracted position in which, when the band deployment sleeve slides longitudinally over the hollow member, the distal portion engages the at least one ligation band. A closing sleeve slidable over the exterior of the band deployment sleeve is configured to constrain the distal portion from the radially expanded position into the radially contracted position. Retracting the closing sleeve proximally over the distal portion of the band deployment sleeve releases the distal portion from the radially contracted position into the radially expanded position.

Abstract: A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.

Abstract: A device includes an anoscope including an elongated hollow member with a longitudinal slot configured to receive tissue in an interior of the hollow member. The device also includes a clip applicator. The clip applicator includes a body slidably received in the slot and jaws at a distal end of the body configured to hold a ligation clip. The clip applicator further includes a plunger slidably coupled to the body configured to actuate the jaws. When the clip applicator is inserted into the slot and the plunger is moved relative to the body, the jaws close and deform the ligation clip from an open position into a closed position around tissue received in the slot.

Abstract: A tissue-engagement member having a pair of jaws movable between a closed configuration and an open configuration, an actuator movable to shift the jaws between the closed and open configurations, and a biasing element biasing the jaws into a closed configuration. The biasing element may be provided over a portion of the tissue-engagement member. A cam mechanism may be provided in operative association with at least one of the jaws and/or the actuator. The biasing element may operatively engage at least one of the jaws and/or the actuator to actuate the cam mechanism to return the jaws to a closed configuration from an open configuration. A manipulator having an actuator-engagement element may be provided to engage an actuation element operatively associated with the actuator. The actuator-engagement element may operatively engage the actuation element in a range of orientations.

Abstract: In one example, a medical device may include a handle including a proximal portion and a distal portion, and the proximal portion may pivot relative to the distal portion. The medical device may also include an insertion portion coupled to the distal portion of the handle and configured to be positioned within a body lumen; and an articulation wire extending from the handle through the insertion portion. Pivoting of the proximal portion of the handle relative to the distal portion of the handle may move the articulation wire relative to the insertion portion to bend a distal portion of the insertion portion.

Abstract: A medical device, for example a delivery catheter, may include a handle portion, a shaft portion extending distally from the handle portion, a deployment mechanism, and an actuation member positioned on the handle portion. The shaft portion may include a working channel and a distal tip portion having a payload chamber configured to receive a payload, such as a bio-absorbable foam. The distal tip portion may be operatively connected to the working channel. The deployment mechanism may be positioned in the working channel, and may be operable to deploy the payload out from the distal tip portion. The actuation member may be actuatable to operate the deployment mechanism.

Abstract: A medical device, comprising a tube including at least one lumen, an absorbent located at a distal portion of the tube, the absorbent being configured to transition from a compressed state to an expanded state, and a structure fixed to the absorbent, wherein the structure is configured to flex into a compressed state and an expanded state simultaneously with the compressed state and the expanded state of the absorbent, and the structure exposes at least a portion of the absorbent.

Abstract: A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.
